It's got to be someone and they're short on true outfielders. Given how strongly they've signaled they want Davis, Morel, and Velazquez playing every day for development, that means you're left with Tauchman, Deluzio(different profile but same complaints you're making above apply), Mastrobuoni (not much of an OF), or Hill(also not on 40 man). An NRI like Tauchman that you can easily DFA when Seiya gets back(since after that point you're likely to be willing to bring up one of the 3 prospects) seems reasonable to me, and the beat writers seem to think Tauchman has an inside track on that spot. They've got an excess of guys on the 40 man for 3B/1B/DH, though. Wisdom and/or Mancini could man RF for a few weeks without needing to drop someone from the roster to add a guy like Tauchman. The defense is likely not as good with Wisdom out there (and definitely not as good with Mancini), but they're both going to give you more offense and it allows AB's to someone like Rios who is a much more likely long-term contributor. With the assumption above about Morel/Davis/Velazquez(plus the obvious exclusion of Alcantara, Amaya, and Canario), the position player options that are already on the 40 man for that spot are...Mastrobuoni. Yes, you could get away with not including Tauchman/Deluzio/Hill for a few weeks, especially if Suzuki is making good progress like he seems he is. But on the other hand, you have 1 free 40 man spot already via Hendricks, and you can probably get another one if you really really wanted to via Rucker. There's multiple guys who might be DFA candidates by May(McKinstry, Hosmer, maybe Wick) so if you do need to make future room for Sanders, Mervis, etc you aren't super limited. Plus it's even easier to get to a full pen with guys already on the 40 man so there isn't an urgent decision you have to make on opening day. There's maybe the potential opportunity cost of keeping Leiter Jr, but he's already seen what the market had to offer him once this winter and came back on an NRI deal, so nothing too significant.
